I IMPROVEMENT IN CHUTES FOR DISCHARGING COAL FROM VEHICLES.

Specification forming part of Letters Patent No. 169,618, dated November9, 1875; application filed September 6, 1875.

To all whom it may concern:

Be it known that I, DAVID P. BITNER, of the city of Lancaster, in thecounty of Lancaster and State of Pennsylvania, have invented certainImprovements in Chutes or Telescopic Tubes for Unloading Goal, of whichthe following is a specification:

This improvement relates to that class of inventions of extension chutesor troughs for conveying coal from a wagon over a pavement into thecellar, without causing dirt or dust to arise from the coal, or injuryto the sidewalk; and consists of an independent telescopic tube,provided with a funnel-mouth or oblique hopper, and bottom hooks, bywhich it can be suspended from the upper edge of the side or end of anyvehicle.

The accompanying drawing illustrates the construction and application ofsaid telescopic coal chute or tube, with the letters of reference makedthereon, and a brief explanation will enable those skilled in the art tomake and use the same, and in which- Figure 1 is a sectional view of thetube extended; Fig. 2, a perspective view of the closed tubes andappliances.

These tubes are in sections, one slidinginto the other, as shown inFig.1. Afunnel-mouth or hopper, A. is connected obliquely with thesection B. This section slides into section 0, and that slides intosection D, as shown, terminated with a scoop-shaped mouth, E, toenter'an open grate, and in front or under the funnel-mouth A are shownhooks G, to hold onto the end gate or side of the wagon, with the hopperor funnel-mouth so inclined as to to adapt it for shoveling in the coal.There are also handles, F, shown on the lower or outer segment D. Thus,when closed together, it occupies but little space, is easily handledwhen made of stout sheet-iron, with flanges a b, so as to lock togetherwhen extended to the full length allowed, and to prevent being drawnapart.

In the mere sliding of one tubeinto another, with arresting-shoulders,as in the telescope or common spy glass, there is no novelty. But, I amnot aware that a tube witha funnelmouth, and made extensile by segmentsfor the purpose of a coal-chute or tube, in combination with the frontclaws and scoop-terminus, was ever used for said purpose, or made,

as herein set forth.

I am aware that sliding and simple tubes have been used for dischargingcoal, attached,

by various modes, permanently, to the rear or bottom of vehicles, formedhopper-fashion, with openings and valves, such as shown in patents No.14,301, February 26, 1856, or No. 73,684, January 21, 1868, and patentMarch 16, 1875, No. 160,861. Such connection or attachment to a vehicleI disclaim, for the' obvious reason that, to attach such to an ordinarywagon or cart, the object aimed at to deliver coal across a widesidewalk is frustrated, without the intervention of a hoistingapparatus, or undue height in the bed or runninggear of such vehicleexpressly made. Therefore,

What I claim as my invention for discharging coal from a wagon acrossthe sidewalk into a cellar is The independent telescopic tubing B O D,with arresting flanges ab, funnel-mouth A, hooks G, scoop-terminus E,and handles F, as

and for the purpose shown and specified.
